Particularly in Europe, this problem was born about ten years ago and shocked the world of cycling, skiing and also football.
A lot of important sport people tested positive at doping checks after a race or a game, all of their sport results lost credibility and their careers were totally compromised.
Media and people made a lot of fuss around this complicate situation and the problem became crisis in a little time.
This phenomenon has existed for a very long time: a lot of cyclists of the past said that sometimes, when they were in difficulty, they were allowed to take a "bomb" that let their performances become higher.
The situation was under control until it became so popular as to oblige governments to take measures against it.
Now the situation is very complicated and it is different for each sport; in general the rules to prescribe a general medicine to an athlete have become more numerous than in the past, in this sense the collaboration of the sport societies is very important.
So, a lot of people are trying to erase the word doping from the sports vocabulary but, so far, without big results.
This is the situation today, few certainties and a lot of questions for a big and complex problem that in the future will exist or not, only if we want.
